Does it have to be that exact word. cause it is just another term for psuedopodium
Not only do ferromagnetic materials respond strongly to magnets (the way iron is attracted to magnets), they can also be magnetized themselves—that is, they can be induced to become magnetic or made into permanent magnets. ... In an unmagnetized ferromagnetic object, domains are small and randomly oriented.
Because of gravity and friction.
The work done by the heat engine is 40 kCal.
The given parameters;
- input heat of the engine, Q₁ = 70 kCal
- output heat of the engine, Q₂ = 30 kCal
To find:
- the work done by the heat engine
The work done by the heat engine is the change in the heat energy of the engine;
W = Q₂ - Q₁
Substitute the given parameters and solve work done (W)
W = 70 kCal - 30 kal
W = 40 kCal
Thus, the work done by the heat engine is 40 kCal.

Hi!
The answer would be ~ 3.58
<h3>Explanation</h3>
You will need to use the simple formula of finding the number of moles, given the mass of the compound, which is:
number of moles of compound = mass of compound / Mr of compound
The mass in this equation is the mass of the compound you have/ are considering.
The Mr is the sum of the atomic masses of each element in the compound.
<u><em>To proceed with this, you need to have two of the following values:</em></u>
Mass : 340g
Mr of MgCl2 : 95
Number of moles : ?
<u><em>Substituting the respective values in the equation:</em></u>
number of moles = mass / Mr
number of moles = 340 / 95
number of moles = 3.58
Hope this helps!
